Quick Answer: What size transformer do I need for LED lights?

To decide how much power your LED strip driver needs, multiply the length of LED tape you have (in metres) by the wattage per metre. For example… This means you will need an LED transformer that can supply 35 watts (at least).

What transformer do I need for LED lights?

All LED bulbs require a ‘driver’ (a special type of transformer) to work properly. Mains voltage LEDs (such as GU10 and B22 bulbs) have the driver built in to the bulb. MR16 and other 12V bulbs use an external driver.

How do I know what size LED transformer I need?

Take the length of your LED strip in feet and multiply it by the watts consumed per foot, then multiply by 1.2. This will give you the minimum sized power supply you’ll need to run your strips.

Do I need a special transformer for LED lights?

All mains powered LED bulbs require a transformer. Depending on the bulb type, the transformer/driver may be built in to the bulb casing or may be located externally.

Can I use 12V transformer for LED?

FAQ – 12V Transformers and LED Compatibility. Magnetic transformers will generally work with all MR16 LED lights, albeit at the cost of efficiency and extra power consumption as was explored in this FAQ article.

Is an LED driver a transformer?

AC LED drivers are actually no-minimum load transformers, meaning they could technically operate low-voltage halogen or incandescent bulbs as well. LEDs, however, cannot operate with conventional transformers because conventional transformers were not made to detect the low wattage of LEDs.

Can I replace 12V halogen with LED?

Yes, in many cases, you can simply replace your bulbs separately, one by one. Furthermore, LEDs can handle all hues of white light, so the warm yellowish light of halogen bulbs is perfectly within reach! …

Can you leave LED strip lights on all night?

Can you leave them on overnight? Yes, LED lights are ideal for leaving on for long periods of time due to their low power usage and very low heat output. They are more suited to use as a night light/ background accent light in general.

How many amps does an LED light strip draw?

Each segment of 3 LEDs draws approximately 20 milliAmperes from a 12V supply, per string of LEDs. So for each segment, there is a maximum 20mA draw from the red LEDs, 20mA draw from the green and 20mA from the blue. If you have the LED strip on full white (all LEDs lit) that would be 60mA per segment.

How many feet of LED strips can you connect together?

Vetco recommends, as a general rule, not to connect more than three complete strips end-to-end without adding in extra, higher gauge power wire or additional power supply units down the line.

What is the difference between a LED driver and a transformer?

What’s difference between LED driver and LED transformer? A transformer is by convention a double wound device, just ac in, ac out. Drivers are more sophisticated than that and usually give a dc output using a switched-mode system, also they have current regulating and monitoring circuits in them.

How many watts do I need for outdoor lighting?

The best wattage for outdoor lights is 80 watts or lower. 40 watts and lower is ideal for lighting pathways and garden beds. 40-80 watts are great for brightening areas like driveways and smaller yards. 80 watts and lower are Dark Sky lighting approved, meaning you’re helping the environment too.

Can I replace 12v G4 halogen with LED?

#3 The compatibility

While replacing 12v halogen lights with G4 LED 12v, it is important to check the compatibility of the G4 LED lights with the lighting fixtures. As mentioned before, most of the G4 LEDs operate on DC voltage, so they will need a different power supply or transformer to operate.

Can I use a halogen transformer for LED lights?

Lower Light Output: It sounds counterintuitive, but the higher voltage from a halogen transformer can actually damage the LED and lead to lower light output. … Buzzing, Dimming, or Flickering Lights: This is a common problem when LED downlights are used without an LED driver. LEDs run on DC power, not AC.

Can I use 12v AC instead of 12v DC?

As long as the voltage of the “DC Appliance” is not less than the 12 Volt adapter then it will either work or won’t, all in all it’s a bad idea to experiment, actually it’s a bad idea just to even think about doing it, unless you know about what you are about to do, don’t.
